The density of butane is highly dependent on temperature and pressure in the reservoir. [19] For example, the density of liquid butane is 571.8±1 kg/m 3 (for pressures up to 2 MPa and temperature 27±0.2 °C), while the density of liquid butane is 625.5±0.7 kg/m 3 (for pressures up to 2 MPa and temperature −13±0.2 °C).
The data about butane density over a range of temperature [−50; +50] °C [4] Vapor pressure of liquid. ... Vapor pressure of n-butane. From formula: ...

Such measurements often use a standard temperature of 25 °C (77 °F; 298 K) [citation needed]. This is the same as the thermodynamic heat of combustion since the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the water produced by combustion is condensed to a liquid.
The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than in the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate ...
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Burn rate (typically expressed in mm/s or in/s) is the sample length over time at a given pressure and temperature. For solid fuel propellant, the most common method of measuring burn rate is the Crawford Type Strand Burning Rate Bomb System [ 3 ] (also known as the Crawford Burner or Strand Burner), as described in MIL-STD-286C.
Example of a color wash in multiple hues. A color wash is a popular technique in faux painting using paint thinned out with glaze to create a subtle wash of color over walls or other surfaces. [1] Color washing gives a surface a translucent, watercolor appearance. [2] It can be used to add texture or accentuate natural surfaces.
